Reaction Conditions

Reaction Steps

To a 100 mL round bottom flask containing 5-bromo-2-chloro-3-nitropyridine (5.12 g, 21.6 mmol) in DMSO (20.5 mL) was added 3-methoxypropylamine (4.40 mL, 43.1 mmol) dropwise. The reaction was heated to 60° C. and monitored with TLC and LC-MS. After 2.5 h, LC-MS showed that the reaction was complete. The mixture was cooled to rt then diluted with water. After extracting three times with EtOAc, the organic layers were combined then washed with brine and dried over anhydrous magnesium sulfate. After filtration, the mixture was concentrated in vacuo to give a light yellow brown solid as 5-bromo-N-(3-methoxypropyl)-3-nitropyridin-2-amine. 1H NMR (400 MHz, CDCl3) δ ppm 8.62 (1H, br. s.), 8.54 (1H, d, J=2.3 Hz), 8.43 (1H, d, J=2.3 Hz), 3.69-3.78 (2H, m), 3.56 (2H, t, J=5.7 Hz), 3.40 (3H, s), 1.96 (2H, dt, J=12.2, 6.2 Hz).
